Overview

In this post we discuss a way of mocking an API server during tests. This technique will let you create a fake API server that can respond to API calls however you want.

The technique is twofold:

• First, we create a mock API handler that extends BaseHTTPRequestHandler, which is the built-in HTTP server class in Python. We can extend the server class to control how it responds to requests - to …

The Genuine AWS Call

Let's start with an example of an AWS API call. Here's how our program will be structured: start with a driver lister.py that creates an AWS secrets manager client and defines a function to list …
